New laser technology matches established method for kidney stone removal
A head-to-head trial found that a newly available Holmium laser with Magneto pulse technology performs as well as the standard thulium fiber laser for minimally invasive kidney stone surgery. The finding matters to hospital procurement teams and urology departments deciding which systems to adopt as laser technology becomes a cost-center decision in surgical care.
Originaltitel: Mini-PCNL using the new Cyber Ho with Magneto technology versus thulium fiber laser: are there any differences?
**Holmium-laser med pulsmodulering matchar fiber-laser i njurstensbehandling** Holmium: YAG-lasern Cyber Ho med ny Magneto-teknik visar jämförbar effektivitet och säkerhet mot thulium-fiber-laser (TFL) vid percutan nefrolitotomi (Mini-PCNL) för stenar ≤20 mm. Studien inkluderade 100 patienter — 50 behandlade med varje laserteknik. Operationstiden var likartad (45,5 respektive 42,4 minuter), liksom stenfrihetsgraden. Magneto-gruppen konsumerade dock mindre energi per mm stenavlösning (7,4 J/mm jämfört med 8,8 J/mm) och krävde kortare lasningsvaraktighet. Italienska Sant'Anna Hospital ledde studien med deltagare från Uppsala University, Madrid och Cambridge. För inköpare och chefsläkare blir relevansen att välja mellan etablerad TFL-teknik och den nya Magneto-modulationen utan att offra resultat — ett avvägningsfall för investering och leverantörskontrakt framför 2026–2027.
PURPOSE: To assess differences in safety and efficacy between Holmium: YAG Cyber Ho generator with Magneto pulse modulation technology (Quanta System MATERIALS AND METHODS: Patients underwent supine Mini-PCNL using TFL Fiber Dust generator (Group A) versus Cyber Ho generator with Magneto technology (Group B). 18 Fr access sheath after pneumatic dilatation, 12 Fr nephroscope and 550 μm laser fiber were used in all cases. Energy and frequency settings were tailored to stone features. Intraoperative parameters, stone-free rate (SFR) and complications were assessed. RESULTS: 50 patients were treated in each group. Preoperative features were comparable. Mean stone diameter was 16.6 vs. 17.8 mm in Group A vs. B (p = 0.18). Mean total operative time (45.5 vs. 42.4 min) and lasing time (11.2 vs. 9.9 min) were similar. In the Magneto group mean delivered energy (8.4 vs. 7.4 KJ, p = 0.05) and energy consumption (8.8 vs. 7.2 J/mm CONCLUSIONS: Holmium: YAG Cyber Ho laser generator with the new pulse modulation Magneto technology has comparable efficacy and safety profile to TFL in the percutaneous treatment of renal stones ≤ 20 mm. Magneto showed a higher dusting efficiency in terms of energy consumption and complete dusting, and a favourable profile in terms of lasing time and ablation speed, despite without statistical significance.
